The Gigabit Ethernet/STM-4 Converter (BD-EOS-GE/STM-4 in short hereafter) takes SDH technology as its core to provide access, convergence, transmission and management functions of TDM services and broadband IP services, and is a device for comprehensive access conversion in the applications of conventional telecommunicating services and broadband data services.

The gigabit Ethernet to STM-4 converter is an Ethernet over SDH interface conversion equipment supplied with two STM-4 optical interface, two electrical Ethernet and two Optical Ethernet interface.

The design of Gigabit Ethernet/STM-4 converter complies with ITU-T and the relevant SDH specifications issued by Ministry of Information Industry, China.

The BD-EOS-GE/STM-4 carries the data services via the container in SDH, realizing the gigabit Ethernet over SDH.

The device applies 19" rack of 1U high, which can be placed on the desktop or installed in a cabinet of 2.2m or 2.6m high, and can directly drive the top-mounted aural-visual alarm unit.

The device can be powered by three power choice: AC ~220V, DC -48V, and AC ~220V with DC-48V backup.
